The deputy chief economist discussed the impact of Western-imposed financial sanctions on Russia with journalist Kirsty Wark on Newsnight.
Ms Ribakova explained how Russia had still managed to make $100bn since the beginning of the year, despite financial sanctions being imposed on the country since the beginning of the invasion of Ukraine.
The deputy chief economist claimed that she still did not believe that the tough sanctions had failed.

“Their budget isn’t surplus as well, because they collecting a lot of money into their… Because of the tax system.”

Ms Ribakova added: “I don’t think sanctions have failed, I just think that we need to try harder, we need to be smarter with sanctions.
“And also not be naive thinking that disconnecting Russia for just a few weeks maybe a few months will be sufficient.
“There has to be a pivot away from working with Russia’s exports, period.”
